Question

In triangle ABC, the measure of angle B is two third of the measure of angle A . the measure of angle C is 20° more than the measure of angle A .Find the measures of the three angles​

Answer 1

Answer:

A=60

B=40

C=80

Step-by-step explanation:

Let A be x

we know that B is 2/3 of A=x

hence B=2/3x

and,

we know that C is 20 more than A=x

hence C= x+20

now,

A+B+C=180   (sum of all angles in a triangle is 180 degrees)

x + 2/3x + (x+20) =180

8/3x + 20 =180

8/3x =180-20

8/3x=160

x=160x3/8

x=60

now we said in the first step that

A=x=60

B=2/3x=2/3 x 60 =40

C=x+20= 60+20=80

hence

A= 60 DEGREES

B= 40 DEGREES

C= 80 DEGREES
